My application is dependent on reading depth information back from the framebuffer. I\'ve implemented this with glReadPixels(0, 0, width, height, GL_DEPTH_COMPONENT, GL_FLOAT, &depth_data)
As far as I understand sending a texture to OGLES2 is done using GLUtils.texImage2D, 开发者_Go百科i.e. I upload the texture to the GPU. How do I send it back to Android then (download it from the GPU)
I tried : process = Runtime.getRuntime().exec(\"su -c cat /dev/graphics/fb0 > /sdcard/frame.raw\");
I was recently struck by a curious idea to take input from /dev/urandom, convert relevant characters to random integers, and use those integers as the rgb/x-y values for pixels to paint onto the scree
My goal is to be able to scale textures when they are loaded, so I don\'t have to do it on every frame the sprite gets rendered. I figured the best method would be to render the scaled texture onto an
I\'m messing around with the framebuffer with OpenGL and JOGL. I have a Graphics obje开发者_Python百科ct, in which I draw.
